Definitions
- the invention relates to a molded synthetic-resin support, i.e. center, particularly for winding machines, of the type known as interlocking supports, for the formation thereon of yarn packages having to be put through dyeing and sometimes also centrifuging operations, the wall of the support or center being perforated to allow dye to flow from the outside in and from the inside out. More particularly the invention refers to a support according to the preamble of claim 1. Such a support is known from EP-A-0536097. A further support having cylindrical and frustoconical surface portions is known from IT-U-0217217.
- the object of the invention is to improve such kind of supports, such as to offer greater resistance to the mechanical and thermal stresses to which these supports or centers are subjected during dyeing (because of the high temperatures reached) and during centrifuging.
- the mechanical stresses are due to many causes that are familiar to experts and are obvious. In particular, stresses during centrifuging are becoming ever greater because of the trend towards accelerating the process of drying by centrifuging.
- the invention makes it possible to achieve great resistance to stresses such as those mentioned above, although limiting the thicknesses and weight of material with a morphology which limits mold costs and molding times, and also achieving adequate uniformity of dyeing by means of the configuration of the perforations.
- the number 1 is a general reference for a support or center which is made from molded synthetic resin for the accumulation upon it of a yam package intended for dyeing by the penetration of liquid dye from the inside out and from the outside in, and for possible centrifuging in order to speed up the drying process.
- the support or center is of basically tubular shape but with a taper to allow successive centers or supports to interlock when fitted on top of each other coaxially and with partial insertion of the top end (when viewing the drawing) of one center in a seat formed in the bottom of another center, as illustrated particularly for the two supports or centers shown in Fig. 2.
- the center has an inside surface 1A that is basically cylindrical for approximately three fourths of the length from the top edge 1 B (when viewing the drawing) of the support, as far as an annular step 1C, beyond which the inside surface of the center, for approximately one fourth of the total axial length of the center or support, has a cylindrical surface 1E whose diameter is slightly greater than that of the surface 1A.
- the axial length of the surface 1E, marked X is about one fourth of the axial dimension of the support.
- the support or center is defined externally by a cylindrical surface 1F that extends for a distance Y of the same order of magnitude as the distance X, that is to say for approximately one fourth of the axial length of the support; the diameter of this section 1 F is approximately equal to the diameter of the inside surface 1E defined above.
- the form of the surface 1G is approximately frustoconical beginning at the larger base 1H of the center, which is the bottom end when viewing the drawing.
- the tubular support 1 is conventionally given perforations distributed appropriately to allow the passage of the liquid dye during dyeing operations. These perforations have been designed to ensure the strength of the support or center in relation to, among other things, the thickness of the support in relation to the above-defined form of the inside and outside surfaces, and therefore in relation to the variable thickness of the center.
- the support comprises a plurality of annular series of slots 3 that extend transversely with respect to the axis of the support, whereas for the remaining part of approximately one half of the total length of the support, this is provided with perforations 5 having greater extension in the longitudinal direction than in the transverse direction, and with a suitably radiused and oval-like outline.
- the perforations 5 are arranged in longitudinal lines with the perforations of one line preferably staggered relative to those of the adjacent lines, for reasons of strength, i.e.
- the support is also given other suitable perforations such as 7 and 9 for reasons of uniformity and distribution of the through holes for the dye liquid.
- Near the larger base 1H is a conventional formation 10 for reasons of functionality of the center and in particular to facilitate the accumulation of a reserve of yarn.
- the distribution of the perforations 3 and 5 in combination with the variation of the thicknesses resulting from the above-defined surface configuration of the support or center, has the effect in the first place of giving the center greater strength than that achieved with the centers or supports of the prior art referred to earlier, thus giving the clear advantages already discussed.
- the second place it is made easily possible to mold individual parts from relatively simple molds and with molding cycle times that permit a substantial cost saving.
- the arrangement described above reduces to a minimum the weight of material required to produce each support or center.

Description
- the inside surface is basically cylindrical for approximately three fourths of the axial length from the smaller-diameter end and has an annular step and a remaining cylindrical internal section of increased diameter for interlocking purposes;
- the outside surface is basically frustoconical for approximately three fourths of the axial length from the larger-diameter end and its remaining cylindrical section corresponds in diameter to said remaining cylindrical internal section for interlocking purposes;
- and for approximately the half of larger dimensions of the wall of the support the perforations are in the form of slots that extend transversely, while for the remaining portion there are perforations that also extend longitudinally.
Claims (3)
- A dyeing support of the interlocking type, for yarn packages having to be put through dyeing and centrifuging operations, said support having a smaller-diameter end (1B), a larger-diameter end (1H) and a perforated wall extending therebetween to allow dye to flow from the outside in and from the inside out, said wall being provided with transversely extending slots (3) and perforations (5) which also extend longitudinally, wherein: the inside surface of said wall has an essentially cylindrical first portion (1A) of smaller diameter, extending for a first axial length of said support starting from said smaller-diameter end (1B), and a second cylindrical internal portion (1E) of larger diameter, for interlocking purposes; the outside surface has an essentially frustoconical portion (1G) and a cylindrical portion (1F) having a diameter corresponding to the diameter of said cylindrical internal portion (1E) of larger diameter for interlocking purposes.
characterized in thatsaid essentially cylindrical first portion (1A) of the internal surface of the support extends for approximately three fourths of the axial length of the support and ends with an annular step (1C), said cylindrical internal portion (1E) of larger diameter extending for the remaining of the axial length of the support;said essentially frustoconical portion (1G) of the outside surface extends for approximately three fourths of the axial length from the larger-diameter end (1H), the remaining portion (1F) of said external surface being cylindrical;and said slots (3) are provided along approximately half of the axial length of the support starting from said larger-diameter end (1H), said longitudinally extending perforations (5) being provided along the remaining half of the axial length of the support. - Support as claimed in claim 1, characterized by including longitudinal ribs (12) extending from said annular step, in order to reduce the interlocking length.
- Support as claimed in claim 1 or 2, characterized in that said perforations have a greater extension in the longitudinal direction than in the transverse direction and with an oval-like outline.
